EGG-OANDLING MACHINE.

To all whom it may concern Be it known that I, 'FREDERIOK E. LEE, a citizen of the i United States, residing at in the county of Grand Forks and State of North Dakota, have invented new and useful 'Improvements in Eg Candling Machines, of which the following is a specification.

This invention relates to improvements in egg candling ortesting machines for determining the fertility or quality of eggsand has particularapplication to machines of that type whereby a plurality of eggs may be tested or candled simultaneously.

efiqciency and durability, one whereby th I, p'ense.

eggs may be candled without the danger of breaking and one which may be manufactured and maintained at a mlnimum ex- Furthermore, I aim to provide an egg testingmachine which will embody in its construction among other features a reflector and a conveyer traversing a path above the reflector and designed to carry" the eggs across the reflector, a source oflight-being provided and disposed above the conveyer so that the same will pass through the eggs and reflect the' images of the latter within the mirror thereby enabling the ca-ndler to view the eggs and determine the quality thereof with accuracy.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings; Figure 1 is a top plan View of a candling machine constructed in accordance with the present invention. Fig. 2 is a central longitudinal sectional view therethrough. Fig. 3 is a transverse sectional view of the same. 4: is a perspective view of one of the trays for the eggs.

Referring now to theaccompanying drawings in detail, the numeral 1 designates a casing constructed of any suitable material Specification of Letters Patent.

and preferably of box-like form r and equipped wlth depending legs 2. This casmg is divided into top and bottom chambers 3 and 4 respectively and the top wall of the bottom chamber is formed with a rectangular opening 5 establishing communicaticn between. chambers of the casing. Suitably secured to the bottom of the lower chamber 4 and inclined downwardly toward the front wall of such chamber is a mirror or reflector 6 while formed in the front wall of the casing is a sight opening 7 equipped-with a hood 8 by means of which the mirror may. be brought into the line of vision of the candler. The opposite end. walls of the upper chamher 3 are provided with vertically movable the top and bottom swinging doors 9, 1O normally held in closed.

position by .means of leaf springs 11, the

door 9 opening inwardly of the respective chamber while the door 10 opens outwardly thereof.

Arranged longitudinally of the chambers and interposed between the same is a conveyer frame 12 extending beyond the oppo-' site end of the casing and havingjournaled in the opposite extremities thereof rollers 13, 13 over which, and rollers 14, 14: jour naled in the legs 2 of the casing at the opposite ends of thelatter is trained an endless conveyer belt 15 equipped with 'crossbars -16 Suitably fasand closing such end is acanopy 17 containing a suitable source of: light, such source being, in the present instance, in the form of an electric lamp 18 connectedin'circuit witha source of current.

In the present instance, one of the rollers 18 is equipped with a crank handle 19 whereby motion may be imparted to the respective roller so that the conveyer belt will be actuated and the latter is adapted to carry the eggs from the inlet side of the conveyer frame into the casing, across the reflector therein and out of the casing by way of the delivery end thereof. In order that the eggs may be safely and conveniently placed upon the belt, I employ trays 20 designed to be placed upon the belt one after the other so-that the eggs contained therein will be successively carried into and out of the casing so that the same may be candled.

In this form of my invention, each tray comprises a substantially rectangular frame 21 provided with a bottom 22 having a group of apertures 23 formed therein to receive the eggs. The capacity of the trays, in thls instance, is one dozen each, but 1t 1s to beunderstood that the trays may be changed, as to size, so that the capacity thereof may be varied, the dimensions of the casing and other parts of the machine being correspondingly varied so as to accommodate the trays.

The delivery end of the conveyor frame 12 has connected thereto a platform 24 of any suitable construction and designed to receive the trays from the conveyer belt 15 as such trays are carried out of the upper chamber. This platform is preferably provided at its free end with a roller 25 to facilitate the removal of the trays therefrom. The front wall of the top chamber 8 is equipped with a sight pening 26 normally closed by means of a curtain 27 and designed for the purpose of permitting the candler to view thelnterior of the upper chamber to determine the position of the trays therein and for other purposes.

In operation, the eggs are placed within the trays and the latter disposed upon the conveyer belt 15 in advance of the cross bars 16 on such belt. The crank handle 19 is now rotated and the belt caused to traverse a path between the reflector and the source of light thereby carrying the eggs into the upper chamber by way of the door 9, across the reflector, and outwardly of the upper chamber by way of the door 10, the trays being-delivered onto the platform 24 from the. delivery end of the belt. As the trays register with the opening 5 in the top wall of; the bottom chamber, the rays of light from. the source within the canopy pass through such ends and reflect images of the latter Within the mirror so that the candler7, by looking into the hood 8 may readily determine the fertility of the eggs.
